Solution

### Step 1. Understanding the problem

First, we start by eliminating unnecessary information. (In this problem, we have a question to the point).

There are 21 sixth-grade Math books on the shelf of the school library. If the total width is 79.38 cm thick, what is the width of one book?

### Step 2. Translation and Evaluation

Translating the word problem into a mathematical formula

Total width of the books in the bookshelf = 79.38 cm

No. of books on the shelf = 21

Width of one book =

### Step 3. Solving it correctly and being specific about the unit

So, the width of one book = 3.78 cm
